3 Claims. (Cl. -70) This invention relates to window sash with drain and more particularly to window sash having a strip at the lower edge of the glazing pane providing one or more drains to carry away water which may accumulate at the lower edge of the pane of glass in the sash.

In glazing window sash it has been customary to proaccuracy of relative dimensions or even of workmanship in setting the glass is not imperative since the strip of putty in plastic condition is pressed in the space between the edge of the glass and the sash simultaneously with forming the triangular putty strip, the operation being by means of a type of spatula, usually called a putty knife. Since the heat of the sun and rain is more persistent against the strip of putty at the bottom edge of the glass, the putty strip at that edge hardens and cracks in a relatively short time, eventually falling in relatively large pieces from the lower edge of the glazing and leaving an open crack between the glazing and the sash resulting in a subsequent seepage of water from rain or melted snow or ice which drips down the glass pane and seeps through the crevice, mostly responsive to wind. In this way much damage is caused to paint or other decoration of the inner face of the window and the casing therearound, and frequently drips down the decorated Wall below the window sill in a room or spoils window curtains or drapes.

The purpose of this invention is to provide a more permanent strip at the lower edge of the glazing and provide therein a drainage for water dripping to or accumulating at such lower edge, designated as slots to distinguish from groove 17 and channel 19.

In brief description of the invention, it comprises the combination of a window sash having an inset rabbet at the perimeter of the inner edge of its opening for receiving the edges of a window pane, the edges of the pane being preferably secured in place by putty at two vertical sides and at the top edge, the horizontal planar strips at the lower edge of the opening of the sash being inclined downwardly and outwardly adjoining and parallel with both sides of the inset of the rabbet, and a strip of molding mounted the length of the outer incline and having an outwardly and downwardly inclined upper face, an inclined lower face conforming to the incline of the on posed face of the sash, the rear wall of the strip abutting the face of the rabbet and having a cutaway chamfer at the juncture of its rear wall and lower face providing a drain channel, and provided with a longitudinal groove at the juncture of the rear wall and upper face for receiving and supporting the lower edge of a pane of glass, the molding having a plurality of relatively spaced inverted grooves in the lower face thereof extending laterally horizontally rearwardly from the exterior face of the sash and communicating with the rear drainage channel, and plurality of secondary drainage grooves extending vertically at the rear wall portion of the molding and communicating between the groove in which the glazing pane is mounted and said rear channel drainage groove.

A preferred form in which the invention may be embodied is described herein and illustrated in the accompanying drawing in which:

Fig. 1 is a fragmentary perspective of glazed window sash showing the invention.

Fig. 2 is a front elevation of glazed window sash illustrative of environment of the invention.

Fig. 3 is a fragmentary transverse vertical section on line 33 of Fig. 2.

Fig. 4 is a fragmentary rear view perspective of drainage strip and glazing pane.

Referring to the drawings in which like reference characters indicate corresponding parts of the several views there is provided a window sash generally indicated 1 having side uprights or stiles 2 and upper and lower cross rails 3 and 4 framing an opening for a glazing pane 6, each of said stiles and rails having a rectangular inset rabbet 5 at the inner periphery of the opening providing a shoulder centrally of the lateral thickness of the sash against which the outer edge portion of the pane of glass 6 may seat, as indicated at 7. The side stiles 2 and the upper cross rail 3 may be well known and conventional, the invention having special reference to the lower rail 4 and its appurtenances, for which reason the inset rabbet of the lower rail is separately indicated 5a.

The lower rail 4 has an inner molding 8 which has a longitudinal planar strip 9 next to and paralleling the wall of inset 5a, the planar face of which is inclined outwardly and downwardly towards the vertical wall of the inset 5a, the outer longitudinal edge of which would, therefore, substantially contact the face of a pane of glass mounted against the shoulder 7. The vertical wall or shoulder of the rabbet 5a of the lower rail may be, and preferably is, substantially deeper than the corresponding walls of the rabbets of the side stiles and upper rail. From the vertical wall of the Sn there extends a horizontal face 5b of the inset portion which extends at an incline outwardly and downwardly.

it is usual to seal the glazing pane 6 in the sash opening by means of a putty strip 10 completely around the edge of the pane, the pane usually being cut to a size a trifle smaller than the dimensions of the rabbetted inset portion of the opening in the sash as at 10a to allow sealing putty to be pressed between the glazing pane and the sash, which practice may be followed in the present invention with relation to the two side stiles and the upper rail.

However, in the present invention the conventional strip of putty is eliminated across the edge of the pane at the lower rail 4, and in lieu thereof there is provided an elongated drainage strip generally indicated 11 mounted upon the lower rail 4 and extending across the lower edge of the glazing pane between the opposite side stiles 2. The drainage strip may be suitably secured to the rail by relatively small finish nails 11a.

This drainage strip 11 has a downwardly inclined upper face 12 and a downwardly inclined lower face 13 which conforms in angle of incline to the upper face 5b of the sash rail, the two opposite faces of the strip 11 preferably being connected at the front by an arcuate front face 14. At its rear the drainage strip is provided with a rear wall 15 having at its top portion a longitudinal rectangular inset 16. The rear wall 15 provides a glazing groove 17 into which the lower edge of the glazing pane is seated in spaced relation to the bottom of the groove 17 by putty cushions 18 which are relatively longitudinally spaced at suitable intervals, for example, 10 to 12 inches apart.

At the juncture of the lower face 13 and the rear wall face 15 of the drainage strip a longitudinal portion of the drainage strip material is removed angularly to both of said wall faces, providing a drainage channel 19 extending the length of the strip when the strip is mounted ii buttsing faces 5a and 5b of the sash as best shown in Relatively spaced lengthwise of the drainage strip 11 it has in its lower and rear faces 13 and 15 a plurality of relatively spaced drainage slots 20 and 21, designated as slots to distinguish'from groove 17 and channel 19. The slots 20 in lower face 13 extend from the outer edge face 14 and communicate with drainage channel 19, and the slots 21 in rear face 15 communicate between the groove 17 of the sash and the drainage channel 19, the two groups of drainage slots thereby communicating relatively through said drainage channel 19. The putty cushions 18 are spaced intermediate the slots 21.

Thus, moisture which may either be penetrated through the groove 17 responsive to gusts of wind, or drip from condensation on the inner face of the glazing pane 6 may accumulate on the inclined inner molding surface 9 and will be directed by the incline towards the pane and will gradually seep into the groove 17. Likewise, water from rain or snow which is forced under the glazing pane will be entrapped in the groove 17 and be drained therefrom by the drainage slots 21 into drainage channel 19 whereupon it may flow through the slots 20 and discharge to the exterior of the sash. While it is preferred that the drainage slots 20 and 21 be aligned substantially in the same vertical plane, they may, if desired, be offset relatively since their relative communication would remain through the drainage channel 19.

Having described the invention, what is claimed as new and patcntable is:

1. In a window sash having a rabbeted opening for receiving a glazing pane and having a lower cross rail, the rabbet providing at said lower cross rail a vertical face wall and a horizontal face wall, the latter being inclined downwardly and outwardly, the combination therewith of a drainage strip having its lower face Wall mounted on said inclined horizontal face of the rabbet and extending the length of the lower rail at said sash opening, said drainage strip having at its rear longitudinal wall a face portion abutting the vertical wall of the rabbet and a longitudinal inset thereabove into the upper portion of said strip and a longitudinal inset therebelow into the lower portion of said strip, the upper inset having a vertical wall and a horizontal wall providing a glazing groove for receiving the lower edge of a glazing pane, and the lower inset providing a longitudinal drainage channel, said drainage strip having a plurality of relatively continuous drainage slots inset in the rear and lower walls thereof and communicating vertically between the glazing groove and drainage channel and communicating horizontally between the drainage channel and the outer face wall of the drainage strip, and a glazing pane having one edge portion engaged in said glazing groove in spaced relation to the horizontal wall of said groove.

2. A window sash structure having the elements of claim 1, the drainage strip having its upper and lower faces inclined outwardly and downwardly.

3. A window sash device of the character described having the elements of claim 1, the lower cross rail having an inner molding having a planar strip next adjacent the rabbet inclined outwardly and downwardly towards the glazing pane groove.
